All Around Finish Symbol

In the finish symbols menu there is an option for "local" or"all around" and the all around adds a little circle on the tail ofthe symbol. When used I interpret this to mean that the entireprofile of the enclosed feature would have this surface finish. Ilove to use it.

Unfortunately, it doesn't appear to be an ANSI or ISO standard andthe shop guys don't know what to make of it.

Does anyone know what standard this comes from? Is it a "legal"callout or a SW invention?SolidworksDrawings And Detailing
